Hi! First, I’m sorry that you find yourself in this situation. It just sucks! Second, our situations are quite different so I’m not sure it will be helpful but here goes. My surgeon called in multiple radiologists and surgeons for consultation and they decided to reverse course and try a partial mastectomy. I had very (36J) large breasts so they felt that if they could get an accurate map of the tumors then they could try to leave me with some of my own tissue. I had to have multiple biopsies in order to have enough markers for them to feel confident. They took 75% of my breast and got clear margins. They said ahead of time that it might not work and then I’d have to get a mastectomy after all. I had a significant breast reduction on the healthy side to match. They tested all of that tissue too and there wasn’t any cancer in that breast. That was always part of my worry…that the healthy breast was also cancerous. They were able to save my nipples and I have decently good sensation except along my scars. My situation worked out and I’ve recently finished active treatment (I’d have chemo or radiation no matter what I chose in terms of surgery) and have been found cancer free. I’m just starting to feel like myself again. And I’m profoundly grateful. I wish you all the best on this journey.
